If it has no mechanism it can't be checked.

The Supra is not an import.
Do you know if that Emissions listing publication is available for anyone to reference?

BTW, I'm pretty sure I can still buy the front pipe without a cat.

This appears to be the O-fficial word on the steet:- http://www.dft.gov.uk/vosa/repository/MOT%20Inspection%20Manual.pdf

DIY ICE enthusiasts had better secure their wiring!

Also sounds like there is no room for a fixed seat.

Sorry, it's now called the "Emissions Data Book" and you can download copies of it here:

http://www.dft.gov.uk/vosa/inserviceexhaustemissionsstandardsforroadvehicles.htm

You'll probably need Section 1. If you download the Excal spreadsheet, you'll need to widen the columns to see all the data, but they need an exact match to be able to put your car through the vehicle-specific emissions test. If they can't find an exact match, it goes on age, so if it predated the mandatory application of cats, you won't need a cat test.

Note also that they're supposed to be on the 17th edition now, so it might pay to check the site again just before your MOT, but it's highly unlikely there will be any changes to entries for older cars.

Interesting. Cars like the Marcos (and I think some other niche sports cars) had fixed seats and the pedal box was adjustable. I assume they're going to add some clarification shortly to say that "fixed seats, if original equipment, are ok"!

Why does it have to be OE? If it hasn't got it they can't test it.

Thanks guys for those links.
I think I'm still a little perplexed though.
gman's link to the MOT manual shows that the emmisions reading for the Supra 7M-GTE should be CO <=3.5% and HC<=1200ppm. From the flow chart in section 7.3 page 6. Cars first used between 1986 and 1992.
This is for a non cat test.
The BET page 8 shows that it is exempt form the BET.
Quote:
Basic Emissions Test (BET) Vehicles first used on or after 1 August 1992 – (1 August 1994 for Class 5 vehicles)

The flow chart on pag 9, about finding an exact match in the database, only refers to vehicles first used after 1992.

But the Supra does appear in the Emmisions Data Book in Avocet's link
shown here:


So the only conclusion I can deduce is that the basic standard of 3.5% and 1200ppm is applied. This is also reinforced by the statement on page 2

Early catalyst equipped vehicles may not require a ‘CAT’ test. The flowcharts and notes must be carefully followed.


I can't see any reference to cars originally equiped with a cat, but no longer having one.

Does anyone arrive at a different conclusion?

My other concern, the '95 Disco now without a cat doesn't seem to be listed at all.
In the "Compression Ignition" section there is no reference to cat or non-cat tests.

If it's not listed I believe they generally do the non Cat test. I had a BMW that was not listed and that's what happened to that.

I could be out of my depth here, but I think the listing in the Emissions Data Book "trumps" age. If it's listed AND AN EXACT MATCH (in terms of VIN, model code, engine type etc), then it gets a cat test, I'm afraid. Have a look in the early section of the emissions part of the Inspection manual in that link. It pretty clearly says the removal of an OE cat is reason for failure.

Of course, as has been said, the converse is true for your Discovery. If it's NOT listed, you're OK.

Easiest thing to do with the Supra is simply to locate a source for a cat, take it for a test, and if it fails for not having one, at least you can order one and probably have it in time for your re-test.
